To all 'whom it mayconcera: Be it knownv that I, JOHN NEWMANN, a citizen of the United States, residing in the city of New York, county of Kings, and State of New York, liave'invented certain new and useful Improvements in Ball-Bean ings, of which the following is a specification.

The present' .invention relates to ball bearings, more particularly to such in which the balls are spaced apart vfrom each other by separators. y j

Its principal object is to provide a ball bearing in which'the balls and separators, once assembled between the so-called inner cone and the'outer shell, will on the removal of said cone not fall apart, but consa vvantage that it can be used with double orvx stitute a unit. Thisn is an important eavture with ball bearings, permitting repairs 2O or inspection without requiring the taking apart of the assembled balls andspacers or separators. There is also the advantage that the balls and separators can be assembled in the outer shell to be ready for use wherever necessary and in connection with any cone suitable for the particular loca# tion of the ball bearing.

Another object of 'my invention is to construct a special 'separator to be used as an end or last separator, which is readily adjustable or capable of extension, so that after its insertion and adjustment, the assembled balls and other-'separators will be locked .in position.

My new end or last separator has the admultiple ball bearings justas conveniently and without requiring force to any great extent, asV with single ball bearings, and

which will permit `the balls and separators Vto be quickly assembled and locked in position. Y

A further and very important object of my invention is to provide a ball bearing which in itself is adjustable, that is to say capable offcnlargement and reduction with respect to the diameter of the balls to allow of the compcnsationfor wear.

With these and other-objects in view, my invention consists in the construction, coinbination and arrangement of parts as will be hereinafter l'ully described and set 'forth' ,in the appended claims.

, In the drawings, which form part of this specification and in which similar refr erence characters denote corresponding f cone and the lil-shaped groove,

parts, Figure l is a side elevation o'li the assembled ball bearing; Fig. 2 is a side elcration of the ball bearing with the inner cone reinoicd showing the balls and separators locked in position ori-.the inner cir- A cuiniference oil the outer -shell and forming a unit therewith; Fig. 3 isa section on line 3 3 ot' Fig.' l, showing the cone made of two annular sections; Fig. il isa similar section on 3, showing the cone Solid and lthe outer shell made of two annular sections; Fig. 5 1s a sectional view of a double bearing with the inner lcone composed of several sections; Fig. 6 is a sectional view of my vend or locking separator; F ig. 7 is a section on line iL-.7 of Fig. 6; Fig. 8 is a side elevation of a modified structure of an end separator; Fig. 9 is a longitudinal section online i0- 10 of Fig. 8; Fig.

10 is a section similar to that of Fig. 6 of modified structure of anend separator; and Fig. 11 is a longitudinal section. of a further modification ot aln end separator.

Referring to the drawing, a denotes the outer shell, b the inner cone, 0 the balls, ai the separators and e the end or last separator for locking the said balls and other separators iu position. ln order to make my ball bearing adjustable to compensate lfor wear, I inalre either part, the outer shell a or the inner cone of two annular halves or sections and shape the circumference of the sections et the split or sectional'part so that when assembled, they will form a Vl shaped groove, while the solid part iS`provided with a spherically shaped groove.

'ln the structure shown in Fig. 3, the inner conei consists of two annular sections b', b2, each of which has a portion of its outer circumference made slanting, as at b",

so that 'when the two parts l2', b2 are aSsembled, they will together term on their outer circumference av Vshaped groove b4'. The outer shell o, on the other hand, in this case is provided with an annular spherically shaped groove e. @wing to the sectional 'Y it will be possible to adjust the ball bearingto compensate for wear. The adjustment can be effected by grinding oil the adjoining` surfaces If', b of the two sections b, b2, thereby raising the bearing points for the balls in the if-shaped groove, or by inserting shiuis (not shown) between the adjoining surfaces bf. b, thereby lowering the bearing points for the balls. The two sections b', b2 of the inner cone ma after all parts are properly assembled be joined tooether in any suit able manner to form a. rigid the present embodiment of my invention, this is accomplished by means of an' inner bushing f, which :may be suitably secured to both sections. In this case, the :innerdiameter oit the sections Zi', h2 of the cone is made somewhat larger than the outer diameter of the shaft, for which the ball bearing is designed, so as to accommodate the bushing f, which is adapted to tit on the particular shaft. By using a thicker or thinner bushing, the inner diameter of the inner cone may be varied according to` diierent thicknesses of shafts.'

ln the structure according to Fig. at, the

inner cone is shown to consist of a single annular member or ring, While the outer shell a is composed. of' two sections or mem-- bers c2. a3, each section having a portion of its inner circumference made slanting, as at et, so that when the two sections are assembled, they will 'together form a V-shaped groove c5, just like the sections b2 of the cone shown in Fig. 3. These sections a?. a3 may he joined together in a similar manner, as the section b', U2, by a ring or outer bushm ing g fitted around the outer circumference olf' said sections, and in which the latter may be lined in any suitable manner. In case of Wear or Where larger or smaller balls are to be used in this hall bearing, the adjoining surfaces a, e7 et the outer shell are ground oli1 in order to lower the bearing points for the halls in .said 'it-shaped groove 0:5 or shims (not shown) may be inserted between the adjoining surfaces a6, el to raise said bear' ing points.

rlhe separators d are oit thensual Well known construction, being at their ends spherically hollowed to :embrace the adjoining balls.

The separator e, which is used as'an end or locking separator, is made adjustable or extensihle so thatnvithout hammering or use of force to any great ertent, the locking' of the assembled parts can be effected.

.fllceording to Figs. 5S and 7, the end or i locking separator yconsists of two head-pieces e', es in forni oftnencated cones, which are spherically hollowed at their ends as the heads or ends of. the-.separators d. @ne of the members or head-pieces, as e, is pro vided with a threaded pin e, which projects centrally therefrom and on Which 'vvorla's the outer head-piece es as a nut, the latter being ',ufo'vided with a central 'perforated and threaded? bore. The threaded pin c so adnams'. l. in length that when the pari-,s c, c2 :ight close together, the free end ot the. A if; e will be still conned within the head-piece c2 so as not to torni an obstruction tothe ball bearing Within the spherical hollow thereof.

single piece. ln

Lee-inea instead of the structure shown in Figs. 6 and 7, the structure shown in Fig. 10 may be used. Here the projection e4 is a smooth cylindrical pin, and the head-piece e vis tightly, but adjustably fitted thereon.

ln Figs. 8 and 9 the en d separator comprises head-pieces e", e8, which are connected together by arched members e9 and which are capable of being compressed or flattened, so that after the insertion of this separator, which normallyV is shorter than the space between two neighboring balls, the members e9 vare compressedfor flattened, in consequence of which the head-pieces, e?, e-B

are extended relative to another and bringr about awlocking of the balls and the other separators d in the saine manner as in the heretofore described structures.

lVith the structures shown in Figs. 6, y7

together either by soldering or by means of a pin 612, or the lilte. When using an end or last separator of this structure, its length may be the same ae that of the other-separators d, 'z'. e., to'exactly t in the space between the neighboring balls. The sections can be inserted consecutively from the tWo sides ci the hall bearing and thereupon joined together.

The principal advantage or' my new separator is that after-the balls and other separators have beenassembled and locked by the last separator, they Will be retained in position and form with the outer shell a un1t, as shown in Fig. 2, so that the innersectional cone can be removed in case or' repair or inspection Without the necessity of taking the halls Vand separators apart. Furtl'ilermore the balls, separators and shell formingl a unit, can be manufactured and held in stock to be ready for use in connection with'. cones of different sizes and to suit various c ditions and locations of the ball bearings. i

Having thus described my invention, hat ll claim and desire to secure by Letters atent is:
